AbstractIn this article, modelling mechanism based on finite element method (FEM) to understand the impact of DC currents on the magnetic loading of the three-phase five-limb transformer IS articulated. This paper provides detailed features of magnetizing current variations and progressions of harmonics in transformer. On variation of primary voltage and injecting DC currents based on a weakly coupled multi-harmonic approach, the three-phase five-limb transformer IS subjected to irregular magnetizing currents with formation of odd and even harmonics based on saturation level of transformer. Furthermore, the scaled transformer IS modelled and it IS visualized that the stray fluxes and the saturation levels of the five-limb transformer raise to a higher level on impact of DC currents of varying magnitudes. The analysis of proposed work IS performed using ANSYS tool for generating the scaled transformer model and MATLAB for plotting the results which validates the proposed concept.
